HENRY c. STRALEY, OF CLEVELAND, onto.

LAWN-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 544,134, dated August6, 1895. Application filed August 29, 1894. Serial No. 521,655. (Nomodel.)

To all whom it may concern:

Be it known that I, HENRY O. STRALEY, a citizen of the United States,and a resident of Cleveland, county of Cuyahoga, State of Ohio, haveinvented certain new and useful Improvements in Lawn-Sprinklers, ofwhich I hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in hose-sprinklers, and its objectsare to provide a simple form of sprinkler which will discharge freelyand sprinkle efficiently.

My invention consists in the curved discharge-nozzle, combined with avertical bolt extending from its top, and a revolving spirally-curvedspraying device placed thereon,-

as will be more fully described hereinafter.

In the drawings, Figure 1 is a side elevation of nozzle with a spiralspraying device. Fig. 2 is a plan view of the same, the spiral sprayingdevice being removed. Fig. 3 is a detailed view of the spiral sprayeralone.

In the drawings, 1 is the nozzle, supported upon the arms 2 and 3extending to the side and rear, the side arms 3 being turned forward attheir extremities to prevent the nozzle from tipping forward. The nozzleis screw-threadedat the pipe-opening or waterinlet, and is taperedtoward the upper end in a gradual curve of large diameter, so as topresent a smooth surface, free from corners,

to the water as the course is changed from horizontal to vertical.

In casting the device a smooth core of metal can be employed and easilyWithdrawn afterward.

At the upper extremity of the nozzle, at 4, is secured the bolt 5, whichsupports the spiral band 6, perforated at each extremity, at 7, toreceive it.

Through perforations 8 in the upper extremity 4: of the nozzle projectsmall streams of water against the spiral band and cause it to revolveat a high rate of speed, thus throwing the Water in a widely-radiatingspray in all directions. This spiral band is cut from a plate of thinmetal in the form shown, and afterward drawn out to complete the spiral.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is-

In a lawn sprinkler, the discharge nozzle provided with the openingsthrough its end for separate jets of water, combined with the pivotalrod which projects above the end of the nozzle, and is provided with astop at its upper end, and the spirally bent plate which extends aroundand revolves upon the rod, and is provided with a ring at each endthrough which the rod passes, and which rings hold the plate loosely inposition, substantially as shown and described.
